I can not use sorting columns in ntreelist. When you try to move the column (swap them), the mouse cursor changes its appearance, but when you release, nothing happens.
EnableColumnReorder is true.
Using UI 2009.1, prior to the acquisition were tested for the temporary license 2008 - may be wrong, but I think there is this feature work.
Please, suggest what am I doing wrong?

Hello Pavel,

Sorry for the delayed response.

Unfortunately, this feature doesn't work in 2009 vol.1 and 2010 vol.1.

Soon we will release a service pack where we will try to include a fix that will allow you to drag and drop columns in NTreeList.

I apologize for the inconvenience.

Regards,

Angel.
